Use Avagadros number to calculate the number of molecules of H2S, the number of atoms of H, and the number of atoms of S, in 5.25 moles of H2S. Show all work and keep track of units and significant figures.

Round probabilities to four places. For example, 0.1234. Show your work. For example, if you are adding two probabilities you could do this: 7/59 + 9/59 = 16/59 = 0.2712.

In advance of the election for 2016 Cobb County Sheriff, Alex and Scott are discussing the different candidates. Scott states: “I haven’t really researched the positions and backgrounds of the two people running. In order to do so properly I would have to invest a great deal of time, and, after all, the chance of my vote deciding the election is very small and I don’t think things will be very different for me regardless of who wins.” His statement is most closely related to the issue of

Question 7 options:

0. Mrs Jones is the owner of a large racehorse stud and horse training business. She employs eight staff and holds a training licence. Mrs Jones’ involvement in the racing business is her full-time occupation and she attends as many race meetings as possible (over one per week). Mrs Jones is also a very keen punter, betting on both her own and other horses, and during the last year she had several very big wins which netted her $120,000 in winnings for the year.

   Discuss whether the receipt of $120,000 is ordinary income under s 6-5.

The Borda Count is a common way of making a choice among more than two alter- natives. As defined in the text, each member of society assigns a rank to the social alternatives (1,2, . . . ), with 1 corresponding to first choice, and so on. The ranks each alternative gets are summed over all the individuals. The alternative with the lowest sum wins; the second choice has the second-lowest sum, and so forth. Set up an example to show that the Borda Count violates the independence of irrelevant alter- natives. Hint: Use a three-person society with three alternatives and rank them using a Borda Count. Then introduce a fourth alternative.

Provide examples, definitions and detailed explanations.

Write a C++ program to score the paper-rock-scissor game. Each of two players (player1 and player2) input a character which could be either ‘P’, ‘R’, or ‘S’ (in uppercase or lowercase). For any other input character should display a message “Invalid input”. The program then announces who is the winner as well as the basis for determining the winner which could be one of the following: “Paper covers rock”, “Rock breaks scissors”, “Scissors cut paper”, or “Nobody wins”. (Use switch statement)

Please do not add up the scores just have a simple quick game and then I would have to reset the program to play again
